How do Intracellular Receptors Differ from Cell Surface Receptors?
Unlike cell surface receptors, which are embedded in the cell membrane and interact with extracellular signals, intracellular receptors are located within the cell. While cell surface receptors rely on second messenger systems to transmit signals, intracellular receptors directly influence gene expression by binding to specific DNA sequences. This fundamental difference highlights their role in regulating long-term cellular processes.
